SIM Disabled / No SIM / No Service Issue With Maybe Workaround - Verizon LG G4

IPosting this more as a FYI from my recent experience with my Verizon LG G4 phone using over seas (Vietnam vs. originally in the U.S.). The phone is currently rooted with firmware VS98610BB (10B) with Android 5.1. The phone is no longer on Verizon Wireless (paid off device and service cancelled). Earlier in the day, my LG G4 experienced an abrupt "SIM Disabled" followed by "No SIM - No Service". I was in the middle of surfing the internet via Viettel's 3G (Vietnam cell phone carrier) when I lost the ability to use the cell phone service. At first, I thought my phone was suffering stability from the drops and banging that happened to the phone recently, however I believe the accidents were negligible due to a soft transparent TPU cover I have on the phone. I then thought that my SIM was probably banned, blacklisted, or blocked from the carrier. I tried restarting the phone. Doesn't work. I removed the battery and reinserted the battery and powered on the phone. Still doesn't work. Finally went to a local Viettel retail store and the representative checked the SIM. It was working in her phone (phone call made to the retail store and phone call made to the phone having my SIM).
I made further searches online to see what other things to try or the possible issues. Saw some may have hardware defects, but in order to eliminate the SIM reader was broken, I decided to whip out the Verizon's SIM to try. The Verizon SIM verified that my phone didn't malfunction. So I was going to try the next solution is to mask the IMEI to verify my SIM was blocked on Viettel's network. I took out the Verizon SIM and stuck in Viettel SIM. To my amazement, Viettel network was picked up again.
I did notice that while I was at the Viettel store, my APN entries were wiped out or erased somehow. I reentered all the APN information but it didn't help while at the the retail store.
Well, the conclusion is: swap SIM into the G4 to see if it resets the network and SIM information, then stick in the SIM you're using.
I hope this is helpful to those who experienced the same issue.

Ran into a similar problem as indicated in the above post (no carrier signal found) with another LG G4 under my care and this time, trying the above workaround did not work for the second LG G4 phone. It appears that something must have corrupted the system files or other files. What I additionally did was cleared out all of the credentials (Settings/Security/Certificate management/Clear credentials). Also, I wiped out the cache by performing Power+Volume down keys on boot up to access boot options of wiping cache (rooted phone). After rebooting the phone one more time, everything went back to normal. What bugged me was that the phone was charged up to 80%. After another reboot, it is now at 100%. Strange. Another thing that was strange was when enabling airplane mode, to disable it from the settings menu was grayed out, i.e., cannot switch off and on. However, the quick settings still worked. But everything is in working order now. This leads me to believe file corruption has happened to both LG G4 phones. Even the APN list was wiped out.

DINC2 unlocked but doesn't recognize SIM in Panama...help!!!

hi. i just got this phone in the states before coming down to panama. it is verizon, but i called them and they gave me the code and now the phone is unlocked....but i can't get coverage here in panama. i've tried sim cards from a few of the local operators and none of them seem to work. i sure hope someone can help....here's what i've done so far: (oh, pls b patient, i'm a bit of a technophobe)
-unlocked sim. phone gives me sim lock is disabled message....that means i'm good to go, right/
-set phone to gsm only mode.
-software is androaid version 2.3.4
verizon global services told me that everything was as it should be and that the phone should work w/ a local sim card so i'm not really sure where to turn to......hopefully someone here can help. verizon also told me that the phone should work on the frequencies here. i have a claro sim card, but have also tried movistar, digicel, and masmovil. i was told that they use either 850 or 1900.
so, i'm totally stumped. hopefully i'm missing something stupid....btw, tried the sim in other phones (from europe and panama) and it worked w/ them. don't think it's a hadrware problem, but am i missing something? is there a setting change? do i need some kind of software update?
thanks!
update- get cell phone reception w/ gps on
don't know if this will help anyone get to the bottom of this issue, but i realized that when i have the gps on, i get full bar coverage. unfortunately, i can't leave the app on in the background. this makes me think it could be a hardware issue....bad antenna? anyone have any ideas
Same problem
I have the same issue as OP. Got my phone sim unlocked, and it runs on SenseMOD-2012-05-18-225643 Android 4.0.4.
For once I did a factory reset, skipped verizon activation (can´t do and won´t work because I´m not in the USA and do not have a verizon SIM or service), set my network preference to GSM/WCDMA, and the network wasn´t working.
Rebooted, my network is identified as soon as it starts, but then it goes to "No Service". Try to search for network but my carrier does not appear.
Any help?
EDIT:
Playing around with the phone, setting GSM as your network and restarting the phone let me make phone calls. No internet though and the APN was configured correctly. The "E" symbol for the internet blinked once in a while, but never got service.
Also, playing around some more, got my phone to not recognize the network again by removing the SIM another time. This sucks.

Sim unlocked, can't use phone on same network

Hi,
I recently went to India and thought it would be cheaper there to get my note 2 unlocked but, the person who tried unlocking my device got mad at me as my phone was rooted. He said, everyone wants to be a developer nowadays and thus it made his job harder. He asked me the model number of my phone as it shows GT-N7105 because I have DN3 v 5.2 installed but it is actually sgh-i317m from Telus in Canada. He gave up and said he was unable to do it. After coming back home, my original sim that I have been using in the same phone, does not work anymore. There is no network. My wife's sim card, which is from another provider, works now though it never did before. I though there could be something wrong with my sim card so I tried it in an old phone and it works perfectly in it. What would you suggest, I should do to try and resolve this problem? I am thinking of erasing everything from my phone and factory resetting it. Eagerly waiting for your expert suggestions!
Just to add: I chose factory reset option from under the settings menu and wiped all my data but it still does not work with my sim. I also, went under the available networks settings, chose the option to search networks and then selected mine (telus) but it say's no service (telus) not available. There is another message in the notification bar, which reads "data roaming: You have lost data connectivity because you left your home network with data roaming turned off". I am not sure if that tells you something related to my problem but I though I should mention that as well.

Note 10+ Factory Unlock Issue

Hi all, I'm new, so forgive me if this is in the wrong section.
I have two Note10+ I got from ATT both with clean IMEIs. I used a factory unlocking service where they send you the code to unlock the phone. The second phone I unlocked worked with no issues. The first one is what has problems. It unlocked however I had PIA VPN active when I unlocked it and it didn't shut down the same way as the other one.When I came back up, it now says Mobile network not available, gives me bars and then says emergency calls only, or flashes between the two.
Steps I've taken to troubleshoot:
Network and factory data resets multiple times
Changed the sim at T-Mobile, where it worked briefly but the boot up screen never changed from at​
The phone is clean on every IMEI checker I have used. I got it working once for about a minute after i went to T-Mobile (it worked and then stopped again). Both phones are from the same ATT account
Mainly I want it to find the signal and download the carrier settings so it doesn't have the fugly AT&T bloatware.
I suspect it may have glitched because the pia app prevented it from shutting down and running some process. Is there a way to force it to "re-unlock" so to speak? Or do I now have an expensive paperweight?

Phone stopped receiving and making calls

hi everyone, i have a lg G7 EMW for almost two years now. as said my phone its an EMW, although I use the EM variant ROM for more than a year because of the lack of updates. never had any issues before.
some weeks ago i had to make a call and noticed it was not working, at first i though it was a cover area issue with my carrier, since it was a place a little far away.
but in the following weeks i started noticing a lot of messages saying 'a number called you and did not left a message' and them i realised that the phone actually never ringed, so i started making some tests and realised it was not making or receiving calls.
i cannot acess all the settings in 'call settings menu' it return me an error saying "network or sim card error" but my 4G internet connection and SMS in the other way, works fine.
I already tried my SIM card in another phone, It worked normal. then i tried another SIM in my G7 and it has not worked also.
i have also tried to go back to my country open rom in a fresh install, but nothing changed.
yesterday after receive a cell broadcast notification, it worked for a short period an them stopped again, so i suspect may be some problem with the network, seems intermittent somehow
have any of you faced similar issue or know any solution? is there something i can do in service menu to see if its a hardware problem?

There were networking changes, so you need a sim card that is compatible with these changes.
If your SIM was purchased two years ago, it may not be compatible.
Just contact your phone provider, whoever it is, and ask them to sell you a compatible LTE Sim card. I had to buy one from Net10/Safelink for 99 cents, because the one I bought two years ago from Best Buy for "Net10" was not compatible with the new changes. All phone service providers should have a "buy your own sim" program, so just contact them for it.
check all necessary information in phone's settings about section.
Is any information missing there or blank?

i can give that a try but i'm not sure, my LTE and SMS seems to work normal, it is only the calls the problem.
the other SIM card i tested on my G7 was from a different carrier and the problem persisted
also my sim worked normal on other phone (Moto G5 Plus)

Call your carrier and ask them if they are using VOWIFI and VOLTE for their calls now.
The phone falls back to 3G mode on calls.
If the SIM or the tower you connect to is not provisioned for VOWIFI/VOLTE, the calls will use 3G.
if the tower is provisioned for VOWIFI but your SIM is not, then the calls will fail. SMS will not fail since that's LTE already.

This problem arises when particular phone has lost phone identification numbers such as S/N, IMEI SV and mainly IMEI. if it's the case then you must try flashing latest stock firmware for you model.

Verizon SIM card corrupting unlocked note 10 Plus

Hi so after I fixed a customer's note 10 plus that had a completely borked and shattered display I decide to put my SIM card in it and restart the device to make a test phone call to make sure everything works before calling the customer telling him his phone is ready. Everything checks out however after I started to notice that the T-Mobile boot screen gets replaced with the Verizon boot screen some junk apps download automatically. Also an error message pops up saying "This is not a Verizon SIM card in this device" whenever a non Verizon sim card is in the note 10 plus which I couldn't get rid of doing everything in the software troubleshooting book (reset network settings, change some cellular settings, factory reset, called cricket and Verizon, etc.) and nothing worked. Didn't really bother the customer but after a week the customer's phone loses all ability to make and receive phone calls/texts, every time you try it just says "this phone is not registered with this network." I tried factory resetting the device and even flashing T-Mobile firmware into it using Odin and still, same bull**** results as before. My question is, has this happened to anyone else here and if so has anyone ever fixed this problem? Uuugghhh.
